OpenAPI Operation Extractor

Extracts every operation in an OpenAPI document (YAML or JSON) into a tab-separated table of method, path, operationId, summary, tags and deprecation status — for pasting into a spreadsheet as an API inventory.

Sample result
Example OpenAPI Operation Extractor result
method	path	operationId	summary	tags	status
GET	/tools	listTools	List tools	tools
POST	/tools	createTool			deprecated
DELETE	/tools/{id}	-	Remove
Next step: Several methods on the same path appear in the order GET, PUT, POST, DELETE.

How to use OpenAPI Operation Extractor

Once a spec runs to thousands of lines, it is hard to see at a glance which endpoints exist. This tool finds every operation under paths — GET, POST, PUT, PATCH, DELETE and the rest — and lists one per line.

The columns are method, path, operationId, summary, tags and status; operations marked deprecated: true show “deprecated” in the status column. A missing operationId is shown as “-”, so gaps are easy to spot.

The result is tab-separated, so pasting it into Excel or Google Sheets splits it into columns automatically. Both YAML and JSON are read, so you can paste openapi.yaml as it is.

  • Paste a YAML or JSON spec into OpenAPI document.
  • Press Run to get the operation list with a header row.
  • Copy the result into a spreadsheet and sort by tag or path.

Useful for

  • Building an API inventory spreadsheet to share with product and QA teams
  • Finding operations without an operationId before generating code
  • Tidying up deprecated endpoints
  • Extracting operation lists from two spec versions to compare them

Limits and checks

  • Paths follow the order in the spec. To sort, use the CSV row sorter or your spreadsheet.
  • Several methods on the same path appear in the order GET, PUT, POST, DELETE.

Worked example

Example input: A list of three operations

openapi: 3.0.3
info: {title: A, version: '1'}
paths:
  /tools:
    get:
      operationId: listTools
      summary: List tools
      tags: [tools]
    post:
      operationId: createTool
      deprecated: true
  /tools/{id}:
    delete:
      summary: Remove

Columns are separated by tabs, and the DELETE operation without an operationId shows -.

Result

method	path	operationId	summary	tags	status
GET	/tools	listTools	List tools	tools
POST	/tools	createTool			deprecated
DELETE	/tools/{id}	-	Remove

Columns are separated by tabs, and the DELETE operation without an operationId shows -.

Common issues

“No operations were found under paths.”

Paths need lowercase method keys such as get and post. Uppercase keys such as GET aren’t operations under the OpenAPI rules.

A YAML error stops the list.

Check the indentation or tabs on the reported line. It’s easier to run the OpenAPI formatter and validator first for syntax and detailed checks.

How to interpret the result

Privacy and review notes

ToolBada runs this tool in your browser where it can. Use sample values instead of personal or confidential data, and review the result before relying on it.

FAQ

Can parameters or response formats go in the table?

This tool lists operations only. Check parameters and response structures in the formatted JSON from the OpenAPI formatter and validator.

Does it read paths split into other files with $ref?

Other files aren’t read. Paste a single bundled spec.

Are the headers in English?

Yes. English pages use method, path, operationId, summary, tags and status as headers, and “deprecated” in the status column.
